.TH HOSTCONFIG 8 "Nov 6, 2000"
.SH NAME
hostconfig \- configure a system's host parameters
.SH SYNOPSIS
.LP
.nf
\fB/usr/sbin/hostconfig\fR \fB-p\fR \fIprotocol\fR [\fB-d\fR] [ \fB-h\fR] [\fB-n\fR] [\fB-v\fR]
     [\fB-i\fR \fIinterface\fR] [\fB-f\fR \fIhostname\fR]
.fi

.SH DESCRIPTION
.sp
.LP
The  \fBhostconfig\fR program uses a network protocol to acquire a machine's
\fBhost parameters\fR and set these parameters on the system.
.sp
.LP
The program selects which protocol to use based on the argument to the required
\fB-p\fR flag. Different protocols may set different host parameters.
Currently, only one protocol (\fBbootparams\fR) is defined.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-d\fR\fR
.ad
.RS 16n
Enable \fBdebug\fR output.
.RE

.sp
.ne 2
.na
\fB\fB-f\fR\fI hostname\fR\fR
.ad
.RS 16n
Run the protocol as if this machine were named \fBhostname\fR.
.RE

.sp
.ne 2
.na
\fB\fB-h\fR\fR
.ad
.RS 16n
Echo the received \fBhostname\fR to \fBstdout\fR, rather than setting
\fBhostname\fR using the system name directly.
.RE

.sp
.ne 2
.na
\fB\fB-i\fR\fI interface\fR\fR
.ad
.RS 16n
Use only the named network interface to run the protocol.
.RE

.sp
.ne 2
.na
\fB\fB-n\fR\fR
.ad
.RS 16n
Run the network protocol, but do not set the acquired parameters into the
system.
.RE

.sp
.ne 2
.na
\fB\fB-p\fR \fIprotocol\fR\fR
.ad
.RS 16n
Run \fBhostconfig\fR using \fIprotocol\fR. Currently, only one protocol
(\fBbootparams\fR) is available. This option is required.
.sp
Specifying the \fB-p\fR \fBbootparams\fR option uses the \fBwhoami\fR call of
the RPC \fBbootparams\fR protocol. This sets the system's  \fBhostname\fR,
\fBdomainname\fR, and default IP router parameters.
.RE

.sp
.ne 2
.na
\fB\fB-v\fR\fR
.ad
.RS 16n
Enable verbose output.
.RE

.SH EXAMPLES
.LP
\fBExample 1 \fRConfiguring Host Parameters with Verbose Output
.sp
.LP
The following command configures a machine's host parameters using the
\fBwhoami\fR call of the RPC \fBbootparams\fR protocol with a verbose output.

.sp
.in +2
.nf
example# hostconfig \fB-p\fR bootparams \fB-v\fR
.fi
.in -2
.sp

.LP
\fBExample 2 \fRDisplaying Host Parameters
.sp
.LP
The following command displays the parameters that would be set using the
\fBwhoami\fR call of the RPC \fBbootparams\fR protocol.

.sp
.in +2
.nf
example# hostconfig \fB-p\fR bootparams \fB-n\fR \fB-v\fR
.fi
.in -2
.sp

.LP
\fBExample 3 \fRConfiguring Host Parameters Less the System Name
.sp
.LP
The following command configures a machine's host parameters, less the system
name, using  the \fBwhoami\fR call of the RPC \fBbootparams\fR protocol.

.sp
.in +2
.nf
example# hostconfig='hostconfig \fB-p\fR bootparams \fB-h\fR'
